Former Patriots video assistant Matt Walsh will meet separately with NFL commissioner Roger Goodell and U.S. Senator Arlen Specter on Tuesday to discuss New England's videotaping of opposing coaches' play-calling signals.

Walsh is scheduled to meet with Goodell at the NFL offices in New York at 7:30 a.m. He will then travel to Washington to meet with Specter, the senior Republican on the Senate Judiciary Committee, who has been critical of the NFL's handling of the investigation into the matter.

Goodell and Specter both plan to hold news conferences after meeting with Walsh.

Patriots coach Bill Belichick was fined $500,000 US, while the team was fined $250,000 and forced to forfeit its 2008 first-round draft choice over the videotaping.

The investigation surrounding the Patriots' videotaping practices began after the NFL confiscated tapes from a New England employee who recorded the New York Jets' defensive signals from the sidelines during the 2007 opener.

Last week, Walsh sent the NFL eight videotapes that showed the Patriots recording play-calling signals. The tapes included signals by coaches of five opponents in six games from 2000-02.

The league said the tapes were consistent with what it already knew.

Walsh worked for New England from 1997 to 2003. His name surfaced just before this year's Super Bowl, nearly five months after the Patriots were sanctioned.

After more than two months of negotiations, lawyers for the league and Walsh finally agreed April 23 to terms under which he would talk with Goodell. They include an agreement by the Patriots not to sue Walsh and to pay his legal expenses and his airfare to New York from Hawaii, where he is now a golf pro.

Specter raised possibility of hearings

Goodell has said that the Patriots could be subject to further sanctions if new information about previously unknown infractions arises.

Specter, from Pennsylvania, met with Goodell in February after raising the possibility of congressional hearings if he wasn't satisfied with the commissioner's answers about the handling of the investigation.

Earlier in February, the Boston Herald reported that an unnamed Patriots employee illegally taped the final walkthrough by the St. Louis Rams before the 2002 Super Bowl, which New England, a two-touchdown underdog, won 20-17.

Walsh's lawyer, Michael Levy, has said his client was not the source for the report.
